Abstract
The Wen River is the only branch after the Yellow River entering Shandong province. Because of good vegetation and little sediment content, the Wen River is a typical clear river in the Yellow River basin. After six water and sediment regulations by the end of 2006, erosion of the entire lower Yellow River from Henan to the estuary was realized as expected. One of the most important findings is that it is successful in preventing the flushing of the Henan reach channel and the silting of the Shandong reach channel at the same time, which people worried most. But we noticed that from 2004 to 2006, during the periods of water and sediment regulations, the Yellow River has received from the Wen River certain order of magnitude floods each year. We used a mathematical model for the Lower Yellow River to study the effect of adding the flow from the Wen River on the effectiveness of water and sediment regulation in eroding the Shandong Yellow River. It is found that the adding of the floods from the Wen River benefit the eosion of the lower Yellow River in the Shandong Province.
